Enum Constant Details

SNAPSHOT

public static final DeltaQueryAnswerType SNAPSHOT

The answer provides a snapshot of the delta query results. That is, the answer is equal to the (possibly truncated) list of results that would be observed if the delta query was evaluated at this specific version of the data store.

DELETION

public static final DeltaQueryAnswerType DELETION

The answer provides a record of deletions from the delta query results. That is, the answer is equal to the (possibly truncated) list of results which would have been returned if the delta query was evaluated on the previous version of the data store, but would no longer be returned if the delta query was evaluated on this specific version of the data store.

ADDITION

public static final DeltaQueryAnswerType ADDITION

The answer provides a record of additions to the delta query results. That is, the answer corresponds to the (possibly truncated) list of results which would not have been returned if the delta query was evaluated on the previous version of the data store, but would be returned if the delta query was evaluated on this specific version of the data store.

Method Details

values

public static DeltaQueryAnswerType[] values()

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DeltaQueryAnswerType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:
